Friendship with Non-Muslims And Respect others faiths

Quran doesn't says that "Muslims should not befriend non-Muslims." Allah only forbids us those who fought against Muslims on account of religion..

Allâh said:

Perhaps Allâh will make friendship between you and those whom you hold as enemies. And Allâh has power (over all things), and Allâh is Oft-Forgiving, Most Merciful{7}.

Allâh does not forbid you to deal justly and kindly with those who fought not against you on account of religion and did not drive you out of your homes. Verily, Allâh loves those who deal with equity{8}

. It is only as regards those who fought against you on account of religion, and have driven you out of your homes, and helped to drive you out, that Allâh forbids you to befriend them. And whosoever will befriend them, then such are the Zâlimûn (wrong-doers those who disobey Allâh){9}
